White River Hardwoods · Traditional Mouldings

Traditional Casing

SKU CA393 · 3-1/2″ W × 1-1/16″ D

Traditional Collection · Solid Poplar · Milled in Fayetteville, Arkansas

Traditional casing from the Traditional Collection for door and window openings, milled from kiln-dried Poplar in 3-1/2″ W × 1-1/16″ D. Ships unfinished, ready to paint or stain. Also available in flexible resin for curved and exterior work.

Made in the USA · Kiln-Dried Poplar · Ships Unfinished · Paint or Stain

Real wood, real grain, milled in long lengths — so a casing run reads as one continuous piece instead of a row of splices.

Construction

How This Profile Is Made

Traditional

Traditional mouldings are milled from solid Poplar. They install with standard woodworking tools and accept paint or stain.

Flexible Resin

The Resin option is cast from the original wood profile, so it carries the same detail and grain pattern and can be stained or painted. It flexes to follow radius walls and arched openings, compensates for framing that isn't true, and will not rot, swell, or deteriorate — rated for interior and exterior use, including bathrooms and sunrooms. The higher price reflects the specialized molding process and the material itself.

Lumber & Machining

All White River Hardwoods hardwood mouldings are milled from clear, kiln-dried hardwood lumber, NHLA graded and dried to 6–8% moisture content. Roughly 65% of the lumber runs 12′ to 16′, which is what lets us produce stock mouldings in overall lengths from 3′ to 16′. Profiles are precision machined on Weinig moulders with Weinig knife tooling.

Why This Profile

The Profile in Detail

Long Stock Lengths

Milled in lengths up to 16′, so most runs go up without a splice. Fewer joints, cleaner line, less filling.

Paint or Stain

Poplar takes paint cleanly and stains evenly. Ships unfinished so the finish is yours to choose.

Standard Tooling

Cuts, copes, and fastens like any hardwood trim. No special blades or adhesives.

Flexible Resin Option

Molded from the original wood model, so it carries the same grain and profile. The flexible resin bends to follow curved walls and out-of-plane framing, won't rot or swell, and is rated for interior and exterior use — bathrooms, sunrooms, and damp locations included.

Please call  1-800-558-0119 and speak to our Customer Service Representative to request an RGA.

*Claims for packages marked "delivered" must be filed after 5 days and before 15 days from the date the package was marked "delivered." Claims for packages presumed to be lost (where the status is not "delivered") must be filed after 7 days (20 days for international) and within 30 days from the last checkpoint.
